T0 all whmn it may concern:

Be it known that I, PHILIP WLLL WALTZ, a citizen of the United States, residing at Vallejo, county of Solano, State of California, have invented anew and useful Wood-Turning Machine, of which the following is a speciby the mechanism illustrated in the accom panying drawings, in which Figure 1 is a vertical section of the entire machine. Fig. 2 is a plan view of the entire machine. Fig. 3 is an end view of the reciprocating cone and revolving knives. Fig. 4 is an end elevation of either end of F' 1,

showing the manner in which the feed-r0 ers operate.

Similar letters refer to similar parts throughout the several views.

A is the frame of the machine; B, the legs or standards of the machine. In the body A turns the cylinder a, which carries the knives b b, which are arranged and slide radially in recesses in the front end of sleeve or cylinder, being held in such recesses by cap-plates b and revolve around in the conical sleeve 0.

The conical sleeve 0 reciprocates in the slides d d and is operated by the Y 1 lower rollshaft, thence up and over the upframe A on cam E.

As shown in Fig. 4, when the conical sleeve;

0 reci rocates on the slides d d the knives b b will 0 ose and spread, as required by the style of Work, and at the same time will revolve around the conical sleeve 0 0 ate. high speed, carrying the guides ff, which hold the knives in firm position. Said guides f f are bars or plates arran ed inside the sleeve 0 and having their en s carried around the ends of the sleeve to connect them and the knives to the sleeves and are slotted or made in spaced pairs to receive the outer ends of the knives, which have heads or lateral ears on their outer ends to lie between said bars or plates and the inside of the sleeve, so that the knives are moved positively endwise or radially in both directions through the guidingrecesses in sleeve a as sleeve 0 is reciprocated by cam E, which engages a radial projection c on sleeve 0. grooved,to permit the inclosin'g ends of guides f to pass through as said guides and knives revolve with sleeve 0.

The cam E is operated by wheel g, riding on top of the wood passing through the machine. Said wheel 9 is fixed on a worm-shaft meshing with a worm-wheel on one end of shaft g, both shafts being mounted in a swinging frame and shaft g having a bevelpinion at its opposite end meshing with another bevel-pinion on a horizontal shaft on which said frame swings to permit wheel 9 to bear upon the work. The last-named pinion meshes with a third pinion on a vertical shaft, which carries cam E.

The weight k is attached to a cord passing over a pulley and attached to sleeve 0 and holds said sleeve up against cam E. v

The forward upper and lower feed-rolls m are mounted in vertically-sliding frames n n The frames n for the lower rolls have rackteeth on their outer edges, and the frames n for the upper rolls have arms extending downward on each side of the frames n, with rack-teeth on their inner sides and spaced from the frames 11, so that cog-wheels k, mounted on the main frame A and interposed between said arms and the frames n, may gear with both racks and maintain the alinement of frames n and n and equalize the movements of the upper and lower rolls to center the work and feed it on a horizontal line. The rolls are yieldingly connected and the lower rolls su ported by cords connected at one end to the flames a, passing under the per roll-shaft down to weights 8.

The double wedge Z is mounted to slide on the outside of the frame A and is used to set the rear feed-roller m for any size work required and is worked by the hand-wheel r, turning a screw threaded into wedge I.

On the feed-roll shafts are bevel-gears, meshing with bevelears splined to slide up and down on vertica shafts u (see Fig. 4) as the rolls move u and down. Said shafts a are bevel-geare to a longitudinal shaft t, which is driven from a transverse shaft y, having a pulley for driving said shaft, and at one end a friction-disk with which engages a frictionulley splined on shaft t to ermit said pul ey to be slid toward or from t e center of said'friction-disk to vary the speed Said radial projection is with which shaft 1. and the feed-rolls are driven by shaft y.

The cylinder at is revolved by a belt that runs between the two cylinder-boxes a: :v.

I claim 1. The combination with a revolving sleeve having knives mounted to move radially therein, of a conical sleeve mounted to slide axially of said first-mentioned sleeve and means to reciprocate the same, the knives being connected to the said conical sleeve to revolve therein but to be moved radially by the reciprocation thereof, by uides loosely engaging around the ends 0 said sleeve in which guides slide the outer ends of the knives said guides being spaced from said conical sleeve to receive therebetween heads on said outer ends of the knives.

2. The combination with a revolvin sleeve carrying radially-movable knives and means reciprocating longitudinally of said sleeve for moving the knives radially, of means for reciprocating said means directly engaging the Work and operated by the travel of the work past the same.

3. A lathe comprising in combination a sleeve carrying knives movable toward'and from the center thereof, means comprising a cam forso moving the knives and a roller engaging the work and rotated by the travel of the latter and operating the said cam.

4. A lathe comprising in combination a sleeve carrying knives movable toward and from the center of said sleeve, means for so moving said knives'comprising a part movable toward and from the center line of said sleeve to directly engage the work and adapted to be moved by the travel of the work past the same and means for transmitting such latter motion to the means for moving the knives toward and from the center of their sleeve and means for causing a relative rotation of the Work and the knives carrying sleeve.

5. The combination with a hollow mandrel-lathe of upper and lower feed-rolls therefor and means for automatically yieldingly supporting and impelling them toward each other of equalizing means tendin to preserve the vertical alinement of said ro ls, comprising lower-roll-carrying slides having rackteeth on opposite sides and upper-roll-carrying slides having arms depending on both sides of the lower-roll slides, and rack-toothed on their inner sides and toothed gears mounted rotatively on the main frame on each side of the lower-roll slides and engaging both sets of the rack-teeth on both the slides.
